The iPhone is a high-carb food source, bringing publishers a steady stream of revenue. Those joining the feast this week come from the world of television (Freeview), newspapers (Metro) and hyperlocal websites (Localpeople).

Since launching at the end of January, freesheet Metro's iPhone app has been downloaded 100,000 times, making it No1 in the free news app category as well as catapulting it to the top 10 of free apps overall.

To be honest, Metro's app is a bit frustrating, as allows the user to see tiny versions of the print pages, which they can browse only by flicking through them. According to Associated Newspapers 20.5% of visitors read more than 20 pages per visit, but afterwards they might be so frustrated that they never visit again.

Operations director Stuart Wood still has high hopes for the app. He said that the page model is attractive to advertisers and he expects to make revenue from the iPhone app. "For advertisers and sponsors, the iPhone app offers further benefits, such as links direct from the newspaper editions to their websites, driving customers and revenue streams," he said.

Like Metro, Freeview's iPhone app is free. The digital service launched a free TV guide as an iPhone app "designed to help viewers plan their TV viewing whilst on the go". That is good. Now you don't have to wait for the fight about the remote with your partner, you can argue on the way home! Plan ahead and catch your favorite shows before your partner bags them as Freeview has a lot of content worth fighting about.

Last but not least in today's iPhone feast is Localpeople, the iPhone app launched by the hyperlocal project of the same name. Localpeople is a network of websites for people to connect in the same area. Initially launched to cover the south-west of England the project has grown from 23 to 70 sites (including London).

The iPhone app enables the user to read the local news nearby and browse businesses in their area using Google Maps. It includes a "top places nearby" feature with content provided by real users, not advertisers.
